my cic and job bank account clarification

[antelao]

I know that I have to create both account.

right now I have complete the express entry form but I DIDN'T submitted.
when I was trying to create an account in the job bank, somewhere i read that I will need a code because I have temporary sin number, and this code is given in a message on my cic account.

if I understand correctly first I have to submit the express entry form, after I will receive the message with the code, and after with that code create the account in job bank, correct?
